High-Tg Covering Film

Product Name:  High-Tg Covering Film

Description 

Polyimide is a macromolecule polymer Polyimide film possess many advantageous properties,such as heat resistance, radiation resistance. film has been the ideal flexible substrate for its physical and chemical performance,perfect used to two layer flexible copper clad lamination(FCCL)and Low secondary thermal shrinking rate, good flatness; Used for FlexiblePrinted Circuit ( FPCB ).

YB flexible laminates are available in a broad range of copper clad constructions using a wide variety of base dielectrics. These laminates are available in either adhesive based or adhesiveless form. 

Adhesive based clads, also known as 3-layer, are made using Polyimide film and are available in sheet form with either SLP FR or LF acrylic adhesive. Also available, under the SLP Brand name, is an epoxy adhesive based 3-layer clad in roll form.

Adhesiveless clads, also known as 2-layer, are available either as double-sided using a lamination based manufacturing process or single sided utilizing cast technology.

Key Features

Initial Production Check (IPC)
Inspection of machinery, materials and accessories to be used for your order prior to production 

During Production Check (DUPRO) / During Production Inspection (DPI)
Control and recommendations for production processes and capacity; this inspection is made 

when at least 20 % of your production is completed. The inspector checks workmanship quality, 

raw materials, product appearance, weight check,size measurements, functionality assortment,

accessories, labelling & logos, packaging, packing and other special requirements depending 

on the product specifications and the export market.

The unfinished products and the compliance with the initial planning of production are also 

verified.
